The POB-400F is a magnetic particle brake with removable feet, designed for smooth torque control in applications requiring slip at set torque levels. It has a torque range of 4 to 300 lb.-ft. and a maximum speed of 1800 RPM. The brake weighs 225 lbs. with feet, has a shaft inertia of 2.1 lb.-in.-sec², and can handle a maximum overhung load of 325 lbs. Heat dissipation reaches 550 watts at 100 RPM and 1200 watts at 1000 RPM, increasing to 1900 watts with piped air at 21 psi and 14 ft.³/minute. The case temperature must not exceed 160°F (71°C). Coil resistance is 6.9 ohms at 68°F and 8.3 ohms at 160°F, requiring a maximum input current of 3.5 amperes and an input voltage of up to 29 V DC. Installation must be horizontal, with shafts aligned and grounded, and flexible couplings used.
Placid magnetic particle brakes, also called powder brakes and mag particle brakes, provide smooth and repeatable torque control. Torque is proportional to input current, and independent of shaft speed, thereby allowing for precise control. These self-contained magnetic particle brakes are ideal for tension control, load simulation, and soft stops. Some large units are available with fan or pneumatic cooling. Torque rating from 1 oz.-in to 300 lb.-ft.
